GEORGE T. REED, OF BALTIMORE, MARYLAND, ASSIGNOR TO JOHN B. H. JEFFERSONAND VICTOR H. KLINEFELTER, BOTH OF SAME PLACE.

HAND DRIVING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 431,994, dated July 8,1890.

Application filed March 14, 1890. Serial No. 343,827. (No model.) I

1'0 all whom it may concern.-

Be it known that I, GEORGE T. REED, of the city of Baltimore, in theState of Maryland, have invented certain Improvements in Hand DrivingMechanisms for Sewing and other Machines,of which the followingis aspecification.

This invention relates to an improved attachment to asewing-machinewhereby the same may be driven by hand-power withoutinterfering with the treadle mechanism, as

' will hereinafter fully appear.

In the description of the said invention which follows reference is madeto the accompanying drawings, forming a part hereof, and in which Figure1 is a side elevation of a sewing-machine table, the fly-wheel, and thetreadle mechanism, together with the improved handpower attachment.Figs. 2 to 11, inclusive, are details of the invention on an enlargedscale.

Similarletters of reference indicate similar parts in all the views.

In the said drawings, A represents the top of the table, and B the legsthereof.

C is the fly-whecl, having the crank-pin a, and D the treadle. Thepitman which con- 'nects the trcadle with the crank-pin is denoted by E.

The above-described parts embody no part of the present invention.

F is a hanger secured by means of screws (not shown) to the under sideof the table A. G is a lever fulcrumed to the hanger F at Z).

H is a connecting-rod pivoted at one end to the lever G and at the otherhinged to a clamp I adapted for attachment to the head of the pitman E.The connecting-rod II is in two parts 0 and (Z, fastened together bymeans of a set-screw e. The part chas a threaded hole to receive theset-screw e, and the other d is slotted, as shown, and fitted withprojections f between which the part c fits. These projections are shownin Figs. 7, 8, and 9, which are respectively a front view, a side view,and a cross-section of the connecting-rod. IVith the above-deseribedconstruction of the connecting-rod H it is evident that it may belengthened or shortened to suit the machine to which the invention is tobe applied, and also to change the angle of the lever G. The outer orfront end of the lever G is made short in order that when the machine isto be run by means of the treadle D it will not be in the way of theoperator; but when the machine is to be driven by hand-power the arm ofthe lever is lengthened by means of a handle J, which is insertedsidewise in a socket g in which the said arm terminates. The front faceof the handle is notched at h to receive the cross-bar t' of the socket,and thereby prevent its withdrawal endwise, and its removal from thesocket laterally is prevented by means of the button One jaw of theclamp I is furnished with teeth 7; and the other with a set-screw m, allof which form slight depressions in the head of the pitinan, which ismade of wood.

The handle J is operated by the right hand of the operator, who guidesthe work with the left.

I claim as my invention In combination with the table A and the head ofthe pitman E, the hanger F, lever G, with its socket extensibleconnecting-rod H, clamp I, and removable handle J, substantially as andfor the purpose specified.

GEORGE T. REED.
